In New York City, a young martial artist named Leroy Green, who idolizes the legendary Bruce Lee, embarks on a quest to achieve the highest level of martial arts accomplishment known as "The Glow." He aims to become a master like his sensei and uphold the values of humility and martial arts purity. His search leads him through the urban landscape, where he must confront villains and prove his skills. Meanwhile, the local arcade magnate and self-proclaimed "Shogun of Harlem," Sho'nuff, sees Leroy as a rival and challenges him to prove who the true master is. Tensions rise as Leroy avoids the confrontation, adhering to his peaceful philosophy.

Parallel to Leroy's journey, a beautiful and popular VJ named Laura Charles is harassed by music mogul Eddie Arkadian, who desperately wants his girlfriend's music video aired on Laura's show. Leroy crosses paths with Laura after rescuing her from Arkadian's henchmen, and a romantic spark ignites. However, as Arkadian's obsession with Laura intensifies, he becomes more dangerous, employing gangsters and even partnering with Sho'nuff in his pursuit of notoriety. Leroy finds himself the protector of Laura, wrestling with his commitment to non-violence while facing escalating threats. His challenges come to a head as he learns about the true nature of "The Glow" and the strength that comes from within.
